On November 26, 2021, the World Health Organization (WHO) classified a brand new variant, B.1.1.529, as a Variant of Concern and has named it Omicron. No instances of this variant have been recognized within the U.S. up to now. CDC is following the main points of this new variant, first reported to the WHO by South Africa. We’re grateful to the South African authorities and its scientists who communicated with the global scientific community and proceeded to share info about this variant with the U.S. Department of Health and Human Services and CDC. We’re working with different U.S. and world public health and business companions to study extra about this variant, as we proceed to observe its path.
CDC is continuously monitoring variants and the U.S. variant surveillance system has reliably detected new variants in this country. We expect Omicron to be identified quickly, if it emerges within the U.S.

CDC recommends people comply with prevention strategies such as wearing a masks in public indoor settings in areas of substantial or high community transmission, washing your hands frequently, and physically distancing from others. CDC also recommends that everyone 5 years and older protect themselves from COVID-19 by getting fully vaccinated. CDC encourages a COVID-19 vaccine booster dose for those who are eligible.
